To determine if 6815 is a prime number or a composite number, we simply look at the factors for 6815.
If the factors of 6815 are only 6815 and 1, then we know that 6815 is a prime number. Otherwise, 6815 is a composite number.
To explain better, if 6815 is only divisible by 1 and 6815, then it is a prime number, and if 6815 is divisible by more than 6815 and 1, then it is a composite number.
The factors of 6815 are as follows:
1, 5, 29, 47, 145, 235, 1363, 6815
